About this tool

Native-speed audio can be genuinely discouraging for a beginner class, and this tool fixes that without turning the speaker into a cartoon character: upload any audio file and adjust the speed up or down while the pitch stays natural. Drop in a listening comprehension track and slow it to 75% for a lower-level class, then bring it back to full speed once they're ready for the real challenge. It works just as well in reverse — speed up a slow recording for advanced students who need more of a stretch. Match the speed to the class in front of you instead of the other way around.
